A surface-mounted 70/100 V, 6.5" 2-way loudspeaker system from QSC, the AD-S6T is part of their AcousticDesign™ series, and is ideal for use in a wide range of foreground and background sound reinforcement applications. It features a high quality 6.5" weather-treated paper cone woofer on a 1.5" voice coil, as well as a carefully selected 1" silk dome tweeter with 1" voice coil that perfectly matches the sensitivity and performance of the woofer for remarkable full-range reproduction. Consistent and even 105° axisymmetric (conical) coverage is attained through DMT™ (Directivity Matched Transition) technology, a QSC innovation which matches the directivity patterns of the woofer and the high-frequency waveguide at the crossover point.
